Which selection is a reason why IGMP snooping should be configured on a switched network?
A.
IGMP snooping populates the snooping table with the results of DHCP requests and can be used by Dynamic ARP Inspection to block IP spoofing attacks at Layer-2.
B.
IGMP snooping verifies the source IP address of every IPv4 packet to ensure that it hasn’t been originated from a port different than its return path.
C.
IGMP snooping is used to filter ping requests and results to avoid overflowing the MAC address table of the switch.
D.
IGMP snooping allows a Layer-2 switch to limit the transmission of multicast frames to only the ports that have members of the relevant IGMP group.
